Jack up the rear of the truck, and secure with Jack Stands about 8" in front of the Leaf spring hangers, then remove the rear wheels.

Remove the rear shock:

Remove the parking brake hangers.

Remove the bolt holding the brake lines to the axel:

Remove "U" bolts, and bump stop:

Lower axel, and attach "C" clamp to leaf pack, near the centering pin:

Remove the centering pin, then remove the "C" clamp:

Place the AAL in between the overload leaf, and the main leaves. Useing the 1/4" socket extension, insert into the centering holes in the springs to align them. Using the "C" clamp again, compress the springs, making sure to keep them aligned.

Install the new centering pin, and tighten down snug. No torque value to this, just get it tight.
Then, Cut the excess threads off the centering pin, leaving about 1/4" of thread exposed, then raise axel back into position:

Looks like you re used the U-bolts, but they don't look stock to begin with (looks like you are getting rid of a rear block kit for an AAL). I'm going from stock TSB to the toytec AAL, should I be buying new U-bolts? I only have about of 3/4" of thread left as it is now...

Actually, We used new U bolts, as the ones used on the block were too long. You should be fine re useing the ones you have.
